Website Domain registered under wordpress.com but not to my account

Hi there! You can read all about using your domain with another host, here: https://en.support.wordpress.com/move-domain/

If you wish to use your domain with another host, you have three options.

Please keep in mind that all three options accomplish the same result.

If you've had your domain for more than 60 days, you can transfer it to a new host by following these instructions: https://en.support.wordpress.com/move-domain/transfer-domain-registration/With a Domain Transfer you would no longer be registered with WordPress as a registrar.

It would appear SiteGround has a guide here involving domain transfers: https://www.siteground.com/tutorials/getting-started/transfer-domains-to-siteground/

If for whatever reason you can't transfer your domain, you can change your Name Servers so they point away from WordPress.com, Your domain will still be registered with WordPress, but you'll no longer be using WordPress.com hosting.

You can change your Name Servers by following the instructions here: https://en.support.wordpress.com/move-domain/change-name-servers/

And finally your host may require you to also update your DNS records, you can do so by following the instructions here: https://en.support.wordpress.com/move-domain/setting-custom-a-records/

It is recommended that you simply transfer your domain, however this may not always be an option.

Finally you can also review the refund policy here: https://en.support.wordpress.com/refunds/

I hope that helps :)
